The perception of a red stop sign can be affected by each individual person's upbringing and how they feel about themselves. For example most of us know that red signifies many things , for example danger, anger, prohibition. But our response to that may be unique.
Some people might be glad to be warned and feel safe and be calm law-abiding people themselves. Others may feel like constant victims being persecuted unfairly and see that sign as a red rag to a bull because they don't respond well to the word 'No.' They may envisage unfair prohibition, or may treat it casually or deliberately or deliberately disobediently perhaps causing deaths.
